`S-UCTION-CONDENSER FOR STEAM-PUMPS.

SPECIFICATION forming part of Letters Patent No. 289,748, dated December 4, 1883.

Application led J' une 6, 18H3.

To @ZZ whom, t may concern:

Be it known that I, TALMADGE BLASS, of Millerton, in the county of Dutchess and State of New York, have invented a new and Improved Suction-Condenser for Steam-Pumps, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved device for condensing the exhaust-steam from any steampump or engine, so as to relieve the piston from the backpressure of the exhaust-steam, whereby the quantity of steam required for running the pump and consequently also the expenses are reduced materially.

The invention consists in a pipe surrounding a perforated part of a steam-pump suction-pipe or steam-condenser, and forming a space between the two pipes, into which space the exhaust-steam is conducted, upon which it passes through the perforations into the water and is condensed. The outer vpipe is provided with an eccentric steamchannel connected with the steam-inlet pipe, which is provided with an automatically-closing valve. Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a sectional view of my improved suction-condenser. Eig. 2 is an inverted sectional plan of the same on the line x Fig. 1. The suction-pipe A of a steam-pump is provided with a series of perforations, a, and the perforated part of the suction-pipe is surrounded by a pipe, B, forming a jacket around the pipe A. The pipe or casing B is provided with an eccentric channel, C, for conducting the exhaust-steam into the space between the pipes A B-that is, the depth of the channel C gradually decreases from the entrance part for the steam to a point diametrically opposite, as shown in Fig. l. The channel O is provided at its widest part with a neck, D, containing a bushing, D, forming a seating for a puppet-valve, E, mounted on a stem, F, guided in an aperture in the suction-pipe in a spider or cross-piece in the neck. The steam is conducted to the neck D by the exhaust-steam (No model) pipe G, which is provided with a three-way co ck, H, 'to permit adjusting the exhaust-steam pipe for exhausting in the air. The condenser is provided with a vacuum-chamber, J, for the purpose of preventing pounding in the suction-pipe. A spiral spring, K, surrounding the stem E, closes the valve E automatically.

The operation is as follows: The steam is exhausted into the air until the water rises in the suction-pipe up to the perforated part, and then the steam issues in jets through perforations into the water, and is condensed instantly. The spring K closes the valve after each exhaust of the pump, thus preventing the Water from the suction-pipe from rushing into the steam-cylinder of the pump.

The condenser is very simple, and does not occupy much space, as it is only a'slight enlargement of the suction-pipe. It does not obstruct the water in the suction-pipe, and operates as well with dirty as with clean water. If desired, the steam of a steam-engine can also be conducted into the condenser.

The condenser can be placed in any desired position.

- Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a suction-pipe having perforations, of the pipe B, surrounding it, and provided with an eccentric channel, C, and of an automatic valve for closing the steam-entrance, substantially as herein shown and described, and for the purpose set forth.

2. The combination, with a suction-pipe having perforations, of the pipe B, surrounding it, and provided With a channel, O, the valve E, the exhaust-pipe G, and the three- Way cock H, substantially as herein shown and described, and for the purpose set forth.

3. The combination, with the suction-pipe A, having the perforations a, of the pipe B, provided with a steam-inlet, and of a vacuumchamber, J, substantially as set forth.

TALMADGE BLASS.
